To all 'whom it may concern:

Be it known that I, WALTER F. STIMPsoN, residing at Detroit, in thecounty of Wayne and State of Michigan,` a citizen of the United States, have invented- 4certain new vand useful Improvements in Scales, -,of

which the following is a specification, reference being had therein tothe accompanying drawings. i I

They inventionl relatesto scales of that type in which the weighing is effected by a variably resisted movement of theweighmg pan, which movement is indicated by a trav-- eling index.

It is one of the'objects of the invention t0- rovide means for returning the index after it has reached the limit 'of its movement by the use of a detachable weight, thus adapt-V -the indication of higher denominations. 5 L I It is a further object'to provide avconvenient arrangement and a simple construction of parts as will be hereinafter set fort-l1. I

In the drawings Figurel is a perspective View of the scale with the weighing platform p removed but indicated by dotted lines.` Fig.

2 is a cross section. Fig.` d `is an enlarged vlew showing the connectlon between the beam, andthe variable resistance and 1nd1- cator. Fig. l is a longitudinal section through the scale. Fig. 5`1is a sectional plan view. A

A is asuitable base, ati one end of this base is arranged the upwardly projecting hollow standard B which carries at its upper end the cross bar C. .This cross barl serves as a supppt for the linkfs D, arranged at opposite ends thereof, and which carry the bearings E forthe fulcrum pivots F ofthe 40 beam. The beam G is arranged to extend longitudinally above lthe ibase, and at -one` end is bifurcated, the. furcations H extending into proximity to the links'D, and car- 1 rying the knife edge pivots F. Thus the fulcrum pivots F are` separated from veach other by substantially the length of the cross bar C, and form a suitable support for the beam, while at the same time the links per.-

l ranged central cross bar C. T

mit of absolutely free movement of the beam. y I is the wei hing platform whichis ary above theistandard B, and

is platform is supported b depending feet J atopposite sides thereo which carry pivotal bearingblocks K, and

the latterV are` Supported @upon edge;

` weight U has been deflected laterally a suili` i extends to the upper end ipivots'L, projecting from the furcations H of the' beam. The platform I is held from lateral movement by the centrali dependl ing rod M, passing within thevhol ow standard B, and connected at its lower end with the pivotallink N fulcrumed substantially 4in thevertical F'of the beam.v

The free end of the b eagh G Vextends above the hollow standard 'O on the base, in which is arranged a dash pot P, this preferably contains oil or other li uid 4retarding me# dium. l'The piston P` o the dash pot lextends upward and 'is pivotally connected to -the beam G. I

Extending transversely of the base, and above the beam Giathe rock shaft Q, this is pivoted at one end in bearing in standard R rising from the base, and at its opposite end in a hollow casing S, also rising, from the base', the casing S contains the index hand T and the variable resistancedl, both of which are connected to the rock shaftQ.

'In the construction shown the variable re-- sistance U is in the form of a pendulous weightthe arm a of which is securedto, and depends from the rock shaft Q. bis

With the construction just described the beam 'X may ,beused as a' tare beam or as ten auxi iar Weights Whntlie article an auxiliary beam. I preferably, however,
